The town of Sineu holds its weekly market every Wednesday morning. Established in 1306 by king Jaume II, it has historically been one of the most important of those that are held on the island. The stands are placed on the church square, on Fossar square and on several streets in the surrounding area. It is the only weekly market with live animals, but it also has fruits, vegetables, crafts, clothes, shoes, etc.

While the market is being held, many visitors stop in the bars to eat the Frit mallorquí, one of the traditional local cuisine dishes, for breakfast.
